A night owl.  I'm working on being an early bird, at least I'm not so grumpy early in the day, so that's a start.

I'm early bird! It is great pleasure for me to wake up early, and do some exercises, or just read some book!)

I'm definitively a night owl person!

I´m an early bird. I prefer to profit the day and doing many things. I love the sun!!!

Saludos!!

@Pavel - You made me laugh with your phrase, "overcome my resentment about getting up early"!  That is a perfect way to put it!  I too am a night owl, BUT I find if I can force myself to get up early, (or I am forced to get up for an appointment, etc.), I am really surprised at how much I can get done in the day.  A day seems to just s t r e t c h  o n  f o r e v e r  if I actually get up at 6am!
